Are you absolutely sure the Long B guy was at 100% before this game was played? Judging by the fact that four relievers were used before Feliz, and that Cooney (at 85%) was used after Feliz, it sure looks like Sparky tried to use every available reliever before going to the tired guys. If the Long B was fatigued below his autorest setting, then all you had left were 3 guys who were tired, and it's not clear how Sparky makes decisions in that case.
As to why Feliz was left in past the TPC of 10, what is his MPC? If his MPC is 20 (or higher) then once he's in the game, since you had only other tired relievers left, Sparky is going to use him beyond his TPC.
I bumped a thread for you where I've tried to outline (as best I can determine) how these decisions are made.
